Also I think that 110v converter device is a nifty addition. If you later buy any of the other battery operated sanders (Delta or RTS rectangle sander) the converter will work with them. I know your feeling-that is a bunch of money for a sander. I went through the same thing last year. Do you know if the battery(s) is Bluetooth or not? That is important whenever you get a dust extractor, but probably not right now.
